He was happy at one point in time, but then people started putting him down. They said things like "you won't amount to anything" or "your mom should've gave you up at birth" then he started asking "why, why is the world such a dark and cruel place?" then he started to use his brain, he started asking what is the meaning of life. He thought about his own philosophy of the world and then he realized if you change the way you look at things you can be happy, but for how long? You have friends, but it's only a temporary fix you'll eventually stop hanging out and you'll wonder where your friendship went. Then you'll start thinking so much that you'll know why, and you'll think to the point where you start to know about the world you'll open you're eyes and see all the negativity that surrounds you and you'll begin to accept it making you a darker person giving off negative energy to the people around you and you'll circle into a depression that grabs on to you, and weighs down on you like elephants trampling over you in a herd that goes on for miles. Your mind starts spiraling out of control and you ask yourself constantly "am i going insane" but the answer is you already are.
